Create pose skeleton
create_pose_skeletonCreate a live stick-figure skeleton from pose data in TouchDesigner. Supports synthetic, MediaPipe, OSC, or existing CHOP sources; outputs a compositable render with adjustable color, width, camera.
Instructions
Render a live stick-figure skeleton from full-body pose tracking — the classic MediaPipe body-tracking look: glowing lines connecting the 33 landmarks (shoulders, elbows, wrists, hips, knees, ankles) drawn by a Line MAT and rendered to a Null TOP you can composite or post-process. Source defaults to a SYNTHETIC animated pose so it builds and previews instantly with no camera and no plugin; switch to 'mediapipe' (the free torinmb plugin), 'osc', or an existing pose CHOP (e.g. from create_pose_tracking) for the real performer. Creates a new baseCOMP under parent_path holding the pose source, a Geometry COMP (a Script SOP that rebuilds points + bones each cook), a Line MAT, a Camera, a Render TOP, and a Null output. Use create_body_reactive instead for glowing dots/trails at the landmarks rather than a connected stick figure. Exposes LineColor / LineWidth / CamDistance. Returns a summary plus a JSON block with the container path, created node paths, the skeleton SOP and output paths, the bone count, exposed controls, any node errors, warnings, and an inline preview image.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| source | No | Where the 33-landmark pose stream comes from. 'synthetic' (default) = a self-contained animated human pose that needs NO camera and NO plugin — use it to build and preview the look instantly. 'mediapipe' = the live CHOP from the free torinmb/mediapipe-touchdesigner plugin (point mediapipe_chop_path at its pose landmarks CHOP). 'osc' = landmarks arriving over OSC (osc_port). 'existing_chop' = a pose CHOP you already built (e.g. the output of create_pose_tracking). | synthetic |
| osc_port | No | UDP port the OSC In CHOP listens on (source='osc'). | |
| line_color | No | Bone colour as hex ('#rrggbb'). Drives the Line MAT; default is bright cyan. | #33ffe6 |
| line_width | No | Bone thickness in pixels (Line MAT near width). Exposed as a live knob. | |
| parent_path | No | Parent network where the pose-skeleton container is created (default '/project1'). | /project1 |
| camera_distance | No | Camera distance on Z. Default frames a whole standing figure in 16:9; larger = further/smaller. Exposed as a live knob. | |
| expose_controls | No | When true (default), expose live LineWidth / CamDistance knobs (+ a LineColor swatch). | |
| existing_chop_path | No | Path of an existing pose CHOP — 33 samples, tx/ty/tz channels (source='existing_chop'). | |
| mediapipe_chop_path | No | Path to the MediaPipe plugin's pose-landmarks CHOP (source='mediapipe'). The plugin emits 33 samples with tx/ty/tz channels. |
